Hey, what size are standar rear brakes?

I have seen this kit: http://www.jam-sport.co.uk/home/ford/mk6...-fiesta-st.html

And was wondering what the part numbers are for the ford parts? I was going to see if I could build that lot myself but with better pads and discs...

I know the conversion is focus st170 rear brakes put on a fiesta best person to advise you is dan the man though

The standard rear discs are 253mm the upgrade is 270mm

It consists of the following

Focus ST 170 splash guards, disc and calliper holder

You will get an increase of 12% more efficient braking, recorded on a brake test and worked out.

Stason what's the increase in the 300mm upgrade

With my 6-pots 325mm i got an increase of 36% more efficiency with vented disc and red stuff pads compared to standard discs and pads from ford.

Thats cool, will it be worth it? Im gettting the front 300mm upgrade too, so hopefully should be able to stop in no time

My 300 mm should be going on at weekend if not next I got calipers and carriers for £10 from scrap yard And discs cost 60 so did green stuff pads all in all 140 with brake fluid

so for the rears, i need:

Focus st 170 splash guards and calliper holders? I'll get discs later when i decide on the make!

What pads would i need?

Would i need a new handbrake cable?

Would I need bolts?

Whats it like to do myself?


I have also been told someone just put the front brakes onto the back, would that work?

I thought It was just splash guard needed for the rear

literally Ash

You need the splash guards and caliper holders bolts are the same, no new pads no new callipers the pads and callipers stay the same.

i got mine done in a garage but Dan knows he did his himself mate, drop him a pm

I had the rear upgrade from JS and it is the best quality money can buy!

Before: (PANTS!)


After: (THE MUTTS!)

I am the mysterious source that told Ash a few people upgrade their fronts then put the old standard fronts on the rear. Makes sense no?

Wow they look good! But i think i'd need redstuff pads so they look right in the calliper

If you are upgrading, I'd be interested in buying your standard ones, if you'd like to sell them?

My front ones? or rears? Sure we can come to some sort of arrangement
